    摘要： An engine cylinder bore with a plated bondcoat and a method of coating the surface of an engine cylinder bore. This method includes electroplating a bondcoat to the surface such that a substantial entirety of its inner circumference that corresponds to a piston travel path within the cylinder bore is covered. Cleaning or related pretreatment operations to properly activate the plated surface helps to ensure a durable coupling of a subsequently-applied thermal spray coating. In one preferred form, the cylinder bore is made from an aluminum-based alloy or a magnesium-based alloy that may be roughened prior to applying the bondcoat, while the bondcoat is plated using a titanium-based material such that a relatively thin TiO2 layer is formed on the cylinder bore. In another preferred form, the thermal spray coating is made of an iron-based material.

    摘要： A method for producing an array of oriented nanofibers that involves forming a solution that includes at least one electroactive species. An electrode substrate is brought into contact with the solution. A current density is applied to the electrode substrate that includes at least a first step of applying a first substantially constant current density for a first time period and a second step of applying a second substantially constant current density for a second time period. The first and second time periods are of sufficient duration to electrically deposit on the electrode substrate an array of oriented nanofibers produced from the electroactive species. Also disclosed are films that include arrays or networks of oriented nanofibers and a method for amperometrically detecting or measuring at least one analyte in a sample.

    摘要： Methods and apparatuses for coating surfaces of medical devices by electroplating are disclosed. In one embodiment, the invention includes a coating method in which a mixture of a therapeutic agent, and a plating material are electroplated onto the surface of the medical device. The electroplating method may be performed at a relatively low temperature to avoid destruction of the therapeutic agent. In another embodiment, a coating method is disclosed in which the coating is formed by suspending a therapeutic agent in an electrolytic solution and electroplating a plating material onto the medical device wherein the plating material carries the suspended therapeutic agent. Thus, the coating of plating material contains the suspended therapeutic agent. These methods and apparatuses are used to apply one or more coating materials, simultaneously or in sequence by varying the electroplating voltage. In certain embodiments of the invention, the coating materials include therapeutic agents and cationic drugs.

    摘要： A method and apparatus for electrochemically forming an oxide layer on a flat conductive surface which involves positioning a working electrode bearing the flat conductive surface in opposed parallel spaced apart relation to a flat conductive surface of a counter electrode such that the flat conductive surface of the working electrode and the flat conductive surface of the counter electrode are generally opposed, horizontally oriented, and define a space therebetween. A volume of organic electrolyte solution containing chemicals for forming the oxide layer on the flat conductive surface of the working electrode is arranged to flood the flat conductive surface of the counter electrode surface and to occupy the space defined between the flat conductive surface of the working electrode and the flat conductive surface of the counter electrode such that at least the flat conductive surface of the counter electrode is in contact with the organic electrolyte solution and substantially only the flat conductive surface of the working electrode is in contact with the organic electrolyte solution. An electric current flows between substantially only the flat conductive surface of the counter electrode and substantially only the flat conductive surface of the working electrode, in the organic electrolyte solution, for a period of time and at a magnitude sufficient to cause the chemicals to form the oxide layer on the flat conductive surface of the working electrode.
